InheritanceverSoundAnalyzer Inheritance Component Inheritance Singleton Inheritance Object

Preforms sound both real-time and pre-time sound analyzation. Real-time analysis includes beat detection, floating averages of overall volume, bass, mid, high, and harmonic. It relies on SoundMixer.computeSpectrum and the FrequencyAnalyzer class by Ben Stucki.
